NBC's "America's Got Talent" returned for another season Tuesday night to score the night's top numbers but still experienced a dip that yielded a series low for its premieres. Meanwhile, in other bad news for singing competitions, "The Voice" saw a new low for its Tuesday results shows, according to preliminary numbers.

"The Voice" at 8 p.m. posted a 3.0/11 -- down 6 percent from last week and a new low for Tuesday results shows -- and had 10.6 million total viewers "Talent" the following hour -- which debuted its revamped judges' panel that includes Hiedi Klum and Mel B. -- had a 3.1/9 and 11.1 million total viewers, making it the top-rated and most-watched program of the night.
